Abstract (en)

[origin: EP4006091A1] The present invention provides a citrate characterized in having an alkyl group derived from an isomer mixture of hexyl alcohol having a degree of branching of 2.0 or less, and if applied to a resin, stress resistance and mechanical properties can be maintained to equal or better levels, and the balance between migration and volatile properties and plasticization efficiency can be kept, and light resistance and heat resistance can be markedly improved.
